What to do about GPS tasks that start out with a remaining time of about 18:00 and then build up to multiple days of remaining time.
The elapsed time will go above the initial remaining time amount.
The progress percentage never gets above one percent.

Using NVIDIA GeForce GTX 1070 with 26.21.14.4166 driver.

I hate wasting an hour or more of elapsed time when I could have finished four or five normal GPS tasks.
I certainly do not like baby sitting the SETI@Home task so I can suspend and abort those tasks.

You would think that BOINC Manager software could use information from the restart checkpoint process to detect these tasks and end them in a reasonable time frame.

If it is a NVIDIA driver problem, I sure hope they can get it fixed. Seems like it has been going on for some time now.

Happy New Year

Once you go past driver version 431.60 you're in that trouble so rolling it back to 431.60 is the only solution at this time.

Cheers.

Noticed in the last couple of day that I have not been getting any run time limit exceeded errors ( I am still getting GPU WU's ). I am wondering if seti is no longer sending Arecibo VHAR workunits,

All that means is that there are no Arecibo VHAR work available, it does not mean that they are being "blocked".

This says otherwise, but the number of VHAR's being sent has dropped a bit (or someone else is getting them instead of me).

Cheers.

No new VHARs will be created unless a tape comes in from Arecibo - and that may be interrupted because of the Puerto Rico earthquake (power outages - I haven't looked for any observatory news). *

But there'll be a background trickle of resends.

* - edit: Arecibo's facebook page says

Good morning! Due to safety inspection protocols after an earthquake, the Angel Ramos Foundation Science and Visitor Center will remain closed. Keep posted, for more details.

NVIDIA released 442.01 drivers on 1/6/2020.
I tested them, and they still have the "SETI OpenCL SoG VHAR on Windows 10" problems:

Maxwell:
> Tasks crash with error.
>ERROR: OpenCL kernel/call 'clEnqueueMapBuffer(gpu_GPUState)' call failed (-36) in file ..\analyzeFuncs.cpp near line 1995.

Pascal/Turing:
> Tasks run indefinitely with no load on the GPU.

431.60 are the last drivers that work correctly for those specific SETI tasks on Windows 10.
NVIDIA is aware, and per NVIDIA, we must continue to be patient for a driver version that includes a fix.

looks like thats a Hotfix driver, not a full release. hotfix released 1/17/2020, based on 441.87 which was released on 1/6

GeForce Hotfix Driver version 442.01
Updated 01/17/2020 12:03 PM

GeForce Hotfix display driver version 442.01 is based on our latest Game Ready Driver 441.87.

This Hotfix driver resolves the following issues:

[Call of Duty Modern Warfare] Streaming of gameplay using OBS will randomly stop
[The Witcher 3: Wild Hunt – Blood and Wine] Game may crash when a user reaches a specific cut scene
[SLI+G-SYNC Stutter] User may experience minor stuttering when using NVIDIA SLI in combination with G-SYNC.

True that. But I wanted to report the result since I did do the test.

I've done a quick update to the Lunatics installer, to include the new ATI files and mention the NVidia driver bug in the documentation. If anyone with one of the affected cards is willing to give it a quick test, could they PM me for a download link, please? (64-bit only so far). Ta.

for what it's worth (if anything)

I'm a new windows-10 user (sigh!) and have an NVIDIA GeForce GTX 1660 SUPER installed so I THINK I'm stuck with the new driver and the eternal looping induced by the interplay of the driver, w-10, and SOG.

My simple-minded solution, that has been working all day now, was to re-install cude50 from the old lunatics procedure.

This run a lot slower BUT - SOG consumed 90% + of the CUDAs and the CUDA 50 consumes about 55% so... I just run 2 CUDA50 and have had NO hanging.

for what its worth

P.S. I have has several tasks "die" at about 15 sec's into the run ... are these the ones that would have looped??

Hi Ed, I had a look at a couple of the tasks that ran in the region of 15 second these tasks are from blc35 data, this is normal behaviour for these types of tasks. I say keep processing them while you can.
That is interesting work around to the driver problem. Thanks for sharing

If you have the right driver, SOG is better as it will produce much more work.
If you don't have the right driver then the old CUDA application is the way to go.

Can anyone tell us how to figure out the download server fanout for the URL for the SAH application. That would solve the issue also.

Maybe since Richard is re-packing the Lunatics installer, he can include the sah app in it. would make the install a lot easier for the Windows guys.

That would be an excellent option. If the user desires to use a newer Windows driver for gaming, then limit the choice to the SAH application only and exclude the SoG application.

I'm only doing an installer for Windows, and there's no nvidia_sah app for Windows on the applications page - only Linux. I'll have a look through my archives and see how far Raistmer got through testing before abandoning sah in favour of SoG.

The latest sah app i found for NV is r3430 which still has the screen lag issue.

That one was a bugfix on 31 March 2016 - it's a long way behind the current r3584 dated 09 December 2016. I wouldn't want to lose r3551 and r3556 - described as 'improvement of validation rate on overflows' and 'massive improvement in overflow validation rate' respectively.

when the new server version was released around Christmas time, the project was sending out the sah app. And as far as I’m aware, it’s sending out the sah app at Beta also.

You can probably get the app and the required files by just attaching to beta and waiting for it.
